Bear Guard Black An old trappers recipe of wild Maine beeswax and real bear grease. Lubricates, waterproofs, conditions, and preserves leather without softening it. BearGuard Black also restores color and repairs scuffs and scrapes. Will not damage glue seams, stitching, laces, uppers, or welts and will maintain flexibility even in freezing temperatures. Does not interfere with the natural breathability of leather and works great for footwear with waterproof, breathable linings. Will not clog, weaken, or rot leather, and does not contain silicone or mink oil.
